Mikel Arteta will now carry the title of Arsenal first-team manager instead of head coach as part of a restructuring that reflects his growing influence at the club.
Arteta, 38, was only appointed in December but an upturn in performances coupled with his leadership throughout the coronavirus pandemic has prompted Arsenal to effectively promote him.

As part of an overhaul which led to 55 non-playing staff redundancies, the departure of head of football Raul Sanllehi and a number of long-serving scouts, the club has also made Vinai Venkatesham chief executive.
Venkatesham, who was previously managing director, will oversee a three-man team responsible for all football affairs as Arteta works closely with technical director Edu and academy manager Per Mertesacker.
Arteta steered Arsenal to a 14th FA Cup success against Chelsea last month and was pivotal in helping convince Pierre-Emerick Aubameyang to agree a new three-year contract.
He was also a key figure in talks over a pay-cut which began soon after the United Kingdom went into lockdown.
Arteta is understood to have held talks with the first-team squad to convince them of the necessity to take a 12.5% pay cut for 12 months. The squad later received 5% back upon qualifying for the Europa League.
